PROTECTIVE COVERING FOR VEHICLE-WHEELS.

SPECIFICATION kforming part of Lettere Patent Ne. 791,502, dated :rune e, 1905.

Application filed November 3, 1904. Serial No. 231,252.

ACoverings for Vehicle-Wheels; and I hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to an improved covering or shield to protect vehicle-wheels from abrasiveA wear, especially'lwheels of the resilient type-such as arevemployed for automobiles, bicycles, and the likeas described in the following specification and illustrated by drawings that form a part thereof.

My improvement Consists in a reversible Vovertire or shield composed of a reticulated web having its warp composed of numerous twisted strands of line metallic wire laid about an elastic brous core and a woof of the same nature and material woven in a peculiar manner, commonly called twilh whereby the warp alone is exposed to wear and the woof protected from abrasion, the whole forming a construction whereby is attained certain qualities and functions that give operative endurance not hitherto accomplished by such shields or coverings.

The object of my invention is to provide a covering or shield for resilient wheels that will be flexible, elastic, non-corrosive, reversible', and as near as possible without inherent sliding action of the members one upon the other, which action with abrasive wear on the surface limits the endurance of such devices.

To accomplish these ends, I provide protective coverings for vehicle-wheels as illustrated in the drawings. ,e

Figure I isa fiat view of a section of my improved covering or shield; Fig. II, an edge View of the same, and Fig. III a transverse section through the rim of a pneumatic wheel with my improved covering applied thereto.

The adaptation to the desired end and the endurance of reticulated coverings for resilient vehicle-wheels have both been limited bedetermined bycertain mechanical laws or rules on which my invention is predicatednamely, first, that fiexure without crystallization or rupture is best attained by subdivision of the bending member, and hence I provide for the warp of my reticulated coverf ing of the width shown a thousand or more -strands of twisted wires, as indicated in the drawing Fig. I; second, endurance of abrasive .wear is attained by the independent stability of the strands composing the warp and woof, so that if a part is worn away the remainder will continuc'to perform the required function and be held 'by the manner of their reticulation; third, inv any reticulated web in which both the warp and woof are exposed to wear the latter is soon destroyed because disposed transverse to the tractive force and to sliding action on the ground.i This is the theory on which my improvement is based and produces a protective covering, as shown in the drawings, now to be described.

' The warp l being composed of twisted strands of non-corrosive wire suiiicient in num- 'ber to produce'the desired width, each warpstrand 1 -is composed of six minor strands twisted about a fibrous core. strand is also composed of six twisted wires, so that each strand 1 contains thirty-six wires, and a web, as shown in Fig. I, with lifty strands 1, composing the warp, contains eighteen hundred separate wires. The border or major strands 2 are made in a similar manner,

with a fibrous core 3, and have each thirty-six wires, preferably of a larger size, because Each minor not exposed to so much iiexure as the body or by means of which latter the covering is held inplace on the wheel-rim 7. In this manner it will be seen that the transverse woofstrands 5 are not exposed to wear, and the warp-strands 1 being twisted and held at each crossing or intersection can be quite worn away without destroying the action and purpose of the covering. It will be understood that the number of strands and of wires in each strand canbe varied to suit the diameter of wheels, the nature of roads where the wheels are used, and that other subordinate structural changes may be necessary or advisable, the general features of my invention remaining the same.

In Fig. III, I show a manner of attaching the covering by means of clips 8, connecting to a ring or wire 9, disposed around and below the extreme diameter of the Wheel-rim 7. This ring or wire is at this'point rigidly held by expansion of the elastic rim when pressure falls on the face at 4C or at the time when the protective covering has to be held firmly in place. TWhen one side of the protective covering is worn, the rivets l0 are taken out, the clips 8 removed, and the covering is reversed or the worn side turned inward against the wheel-tire 7 so there will be a new face with an endurance much the same as in the first use.

Having thus described the nature and objects of my invention and manner of its use, what I claim as new, and desire to secure by Letters Patent, is-

1. In resilient vehicle-wheels, a protective covering consisting of reticulated web, twillwoven, the warp alone exposed to wear, the warp-strands composed of multiple twisted wires disposed and operating in the manner substantially as described.

2. In resilient vehicle-wheels, a protective covering consisting of a reticulated web, twillwoven to expose the warp alone, the warp and Woof composed of multiple strands of metallic wire, the woof double and passing over border or major strands at each side of the web, substantially as specified.

3. In are silient vehicle-wheel, a reversible protective covering, consisting of a reticulated web, woven to protect the Woof, the strands composed of multiple twisted wires wound about a librous core and means to removably attach the covering to the resilient tire of a vehicle-wheel, substantially as specified.

4. In a resilient vehicle-wheel, a protective covering composed of a reticulated web disposed in twisted strands of multiple wires, a major strand at each side of the web around which the woof passes, and removable clips or other suitable fastenings that permit the covering to be reversed when worn on one side, substantially as specified.

In testimony whereo I have signed my name to this specification in the presence of two subscribing witnesses.
